If you don’t use your trademark, it could become a zombie. %CUT% Macy’s Department Stores has been absorbing local department stores and their trademarks for decades. Once Macy’s takes over, it rebrands the store. But, those old department store trademarks still exist in the minds of the consuming public. In other words, the dead trademarks became zombies. Seeing the marketing potential of zombie trademarks, Strategic Marks started selling T-shirts using them. Macy’s filed a trademark infringement suit against Strategic Marks and won. It helped that Macy’s hadn’t really abandoned most of the trademarks. It was using them in its “Heritage Collection”. In the end, the parties settled and Macy’s transferred some trademarks to Strategic Marks.
